I have one of Hahn Rossman's frame alignment gauges which I like a lot. Note that it has a 135 size which I'll never use (yeah, I know, never say "never") but lacks a 126 size which, looking around my bike "collection," I see I can definitely put to use. I don't know if Hahn ever made a 100/120/126/130 tool, but if he did and you have one just gathering dust in your shop, how about we trade?
